IThe `traces 'pass through Iskeleton rollers@ eachof,ulrich isfadapte'dtofloe rocked from "eltfe on 'positron orvice :versa by the 1n- (itl dividual or associated operating prnember, such as a stop key vor pedal, these operating members not being shown in the drawings irs they -are well-known in vthe art. The traces are 'carried for longitudinal movement on a suitable pan c. Each trace carries an armature j' operated by a respective niagnet g. Each of these magnetsg lhas an associated thumb piston or pedal. hese pistons are not shown with the exception of the one for the trace in which is embodied the improvements olf the present invention. Coinn mon to all of the pistons rand the magnets g isa solcnnid 7L which, when energized, moves an impellr towards the right, referring to Figs. 1, Q and 3. The spring 7c returns the in'ipeller when the solenoid LV is vCle-energized. Tliego'peration of the construction so tar described ywill be clearly understood from my Jforegoing patents, it being here sufficient tosay ythat when it is desired to yrecord any selected combination on one of' the traces a, the piston associated with that trace is pushed in, thereby `energizing ythe respective n'iagnet y] which lifts the yarmature j' associated with that magnet into ythe path of movement of the impeller fi. Also, when the piston is pushed in, 'the solenoid L is energiaed so as to advance the impeller i and that 'tracce the armature f of which has been raised. Then, while the piston is held in to maintain the parts in advanced position, tlie selected rollers are individually rocked so as to set the desired actuators in operative or stop drawing position. Thereatter, the piston is drawn out or released, with theiresult that the trace is returned by a respective spring m to inoperative position.

lith traces constructed as just described, it isnecessariy, in order to record any given combination of stops, to hold the trace on which the combination is to be recorded in advanced position and manually and'individually operate the keys or pedals of the respective rollers associated with the stops which it is desired to record; whichmeans that, in the event it is desired to record a selectedcombination of stops during the rendition oj a composition, it is necessary to interrupt the playing. It is noted that the actuators are always locked in their opera tive or inoperative position so that, when the trace is advanced. the actuators will turn the rollers with which they come into engagement. 'lheytraces a may constitute what are called generals, that is, they may be elective in all Hdivisions of the organ, or they may represent traces which are etl'ective on only certain divisions of the organ.

In accordance with the present invention, .I vprovide a. trace mechanism with actuators or cams normally loosely mounted on the trace sok that, whenV the artistl operates. the piston, pedal, tablet, or other operating member of that trace to advance the latter, the cams respectively associated with the stops which have beendrawn will'be rocked into operative .position by 'their engagement with the actuated rollers of those stops, and all of the cams, after certain ot' them have been rocked to operative position as just described, are locked against movement relative to the trace by a bar. Then the trace ywith the cams locked thereon is returned to moperative posit-ion and when the artist desires to again call into play the combination of stops recorded, it is merely necessary `for him to push in the piston associated y'with my improved trace, thereby advancing .the latter and causing the cams to rock hose rollers,

vwhich are not in desired posit-ions, simultaneously into the desired positions and without the necessityof manipulating the stop keys or pedals. The selected combination ot stops may be recorded after each time the selected combination of stops has been played, or the combination may be varied at will and the modified combination recorded without interru'ptin;r the playing of the composition. Y

Referring more specifically to the drawings, 10 designates the trace of my improved mechanism. This trace is mounted for reciprocation in the trace pan e and carries the cams or actuators 11y for rocking t-he rollers d. The rearwardly extending portion of each cam overlaps the forward end of the next preceding cam and is provided 'with two ythe actuators spring apart laterally to assume the position shown in Fig. 5. 2O designates a locking bar mounted for limited floatingr movement on the trace 10. In the present illustrative disclosure, this bar is supported on the trace by brackets or staples 21, the staples being preferably spaced in accordance with the distance between the pivotal points of the cams. The staples are so positioned as to bridge the cams at their overlapping points. The arrangement is such that the staples prevent the actuators from being unhooked from the trace 10 during the unlockingy movement of the bar, and the staples limitr the downward movement of the actuators. y

c The locking bar is provided with lateral projections or bosses 22 which are. spaced in accordance with the spacing of the actuators los) ll. lWhenytlielockingfbar isin the unlocked v out otengagement Witlithe bosses on' the*y :cams 11 so that all of the caniso'r actuators lare unlockedand are, there-tore, lree to be position shown in Fig.v k1, the bosses 22 are rocked uponian advanc-ingy movement of. the

spectivev stop rollers Which are in onposif tion. When the bar is in theflo'cliing position shoivn'in'Fig. 2, tliebos'ses thereon engage the opposed bosse-s of the actuators, thereby `springing theser actuators'vsothat the heads of the' studs' 14r engage lin the re'- cesses `provided by the bossesl, which meansl that the' actuators are ylocked against rockingmovement."`

thatin Wliiclithe othertraces a fare advanced and, to this end,the tra-ce 10 j may have (an armature 30 controlled byv a magnet 3l which,

lin turn'is controlled by a thumb piston 82. The numeral'i designates an intermittently rotated release yWheel adaptedto cooperate Withfthe rear end of theflockingfbarfa as hereinafter described v more in kkdetail. 'This release Wheelis longery than itis wide so as to provide a `pair of` arms 36,'so to speak. The release Wheel is: fixed rto a stub yshaft 37 journalled in af'stationarybracket nand has, extending from its face, ratchet lugs 39. Fixedon the ,shaft' is a'bushing i l0 between vwhich.'andthe ybracket is interposeda spring 41 rfor preventing'the Wheel y Atroniover-running(` The rotation ofthe release Wheel' is controlled by afpawl l2 piv-l Lotally mountedoii the rearmost stud othe main trace and has a hooked portion e3 f f adaptcdftofengage the lugs 39.- /Vitli this ar- .{iiangement, on eachV rforward ymoveifiient-I 'of y the itrace 10, the Wheel' yWill be rotated 9,00 `or aquarter ot a. revolution.

maining actuators in their lowermost yor stop t cancellingposition. Furthermore, upon the t'orivard movement of the trace' 10,'tlie'wheel 35 is, rotated a quart-eroi a revolutionr from the position shown inFig. l to that f shown] in Fig. 2. kThe desiredcombination now having been lrecorded kon ythe t lace '10,* the Y piston i'isreleased -or.-draivn,out, Whereupon the spring'r25 Willwithdraw the trace lines Fig. 2 and, upon-this return 'movement prima the ioeiiing bei Wiiiiock @i noia those.

At the iso iso 1 the Wheel holds the locking bar against endivise movement, the bosses o't the actuators will ride from under the projections on the locking bar with the result that 'those actuators which have been in raised or stop drawing position will drop ot' their own Weight into normal or stop cancelling po'ition, and the various elements will assume the unlocked position shown in Figs. l and 5. The force of the spring 25 is sufficient to break the friction holding the parts in locked position, so as to ellect the unlocking thereol when the circuit is opened by releasing the thumb piston. After the particular movement has been re-played, the same stop combination may again be y recorded by simply pressing the piston or the recording mechanism may be held in readiness 'tor recording a stop combination of different tone colors which are especially suited to other movements as they may develop. It will be seen trom the 'foregoing that each time the trace mechanism is returned to inoperative position after it had been advanced to operate the stop rollers, the trace mechanism is unlocked and is in readiness for "ecording a diti'erent stop combination; or the same movement, such as a theme, may be intermittently repeated an;v number of times by recording the stop conibination during the playing or at 'the conclusion olE each repetition thereof; that to say, at any time before the stops, 'which have been drawn on and which it is desired to record, are disturbed depending upon `the instant at which the artists thumb or tinger is near the piston While playing.

Preferably, the recording trace mechanism is effective in all divisions of the organ; that is to say, every stop on the organ console will have a corresponding actuator on the recording mechanism. It is obvious, therefore, that a stop combination may include couplers combined with the speaking stops and various other combinations may be had. rlhe thumb piston for operating the recording mechanism may be conveniently locate-d on the levier name board of the organ console and, in case a pedal is used separately or with the thumb piston for operati the trace l0, it will beconveniently loca-ed on the toe board.

In the ilraivings, I have shovvn but one of my improved recording trace mechanisms, but, obviously, the organ may have any desired number of such mechanisms,

As many changes could be nia-do in the above construction and many apparently .videly different embodiments of this invention could be made Without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying' drawing shall be interpreted as illustrative and not in a limitingsense.
